Description
Retinoic acid (RA) is a potent inducer of cell differentiation and plays an essential role in sex-specific germ cell development in the mammalian gonad. RA is essential for male gametogenesis and hence fertility. However, RA can also disrupt sexual cell fate in somatic cells of the testis, promoting transdifferentiation of male Sertoli cells to female granulosa-like cells when the male sexual regulator Dmrt1 is absent. The feminizing ability of RA in the somatic testis suggests that RA might normally play a role in somatic cell differentiation or cell fate maintenance in the ovary. To test for this possibility we disrupted RA signaling in somatic cells of the early fetal ovary using three genetic strategies and one pharmaceutical approach. We found that deleting all three RA receptors (RARs) in the XX somatic gonad at the time of sex determination did not significantly affect ovarian differentiation, follicle development, or female fertility. Transcriptome analysis of adult triple mutant ovaries revealed remarkably little effect on gene expression in the absence of somatic RAR function. Likewise, deletion of three RA synthesis enzymes (Aldha1-3) at the time of sex determination did not masculinize the ovary. A dominant-negative RAR transgene altered granulosa cell proliferation, likely due to interference with a non-RA signaling pathway, but did not affect granulosa cell specification or fertility. Finally, culture of fetal XX gonads with an RAR antagonist blocked germ cell meiotic initiation but did not disrupt sex-biased gene expression. We conclude that RA signaling, although crucial in the ovary for meiotic initiation, is not required for granulosa cell specification, differentiation, or reproductive function. Overall design: Ovaries from six week old mice with five replicates in each of two genotypes were analyzed by RNA-Seq

Description
Purpose: Controlling the balance between immunity and immunopathology is crucial for host resistance to pathogens. Upon infection, activation of the hypothalamic-pituitary-adrenal (HPA) axis leads to the production of glucocorticoids (GCs). However, the pleiotropic effects of these steroid hormones make it difficult to decipher their precise role in vivo. Our purpose was to study how GCs regulate the function of group 1 ILCs in spleen and liver upon Murine Cytomegalovirus (MCMV) infection. Methods: We studied the in vivo effect of endogenous GCs released upon MCMV infection on NK cells in spleen and liver and ILC1s in the liver. We compared WT mice with GRNcr1-iCre mice, in which the gene encoding for GC receptor (GR) is selectively deleted in Ncr1+ cells. Results: We found that the regulation of NK function by the GR is required for host protection against MCMV. Mechanistically, endogenous GCs produced shortly after infection induce the selective and tissue-specific expression of the immune checkpoint PD1 on NK cells. This GC-PD1 pathway mediates its immunoregulatory functions by limiting interferon (IFN)-g production by splenic NK cells, preventing lethal immunopathology. Importantly, this regulation does not compromise viral clearance. Conclusions:The fine-tuning of a selective subset of ILCs by the HPA axis preserves tissue integrity without impairing pathogen elimination, revealing a novel aspect of neuro-immune regulation. Overall design: Splenocytes (after NK cell enrichment with the mouse NK Cell Isolation Kit II, Miltenyi Biotec) and liver lymphocytes were pooled from three mice for each genotype. A FACS Aria III (BD Biosciences) was used to sort approximately 5 x 10^5 NK cells from the spleen and liver and 5 x 10^4 liver-resident ILC1s 44h post MCMV infection. We compared gene expression between glucocorticoid receptor (GR)-sufficient and deficient ILCs to identify the genes whose expression is regulated by GCs. Three biological replicates were generated for all samples except for the GRNcr1-iCre liver ILC1s sample (two biological replicates).

Description
Natural killer (NK) cells are NKp46+CD3- lymphocytes that can perform granule-dependent cytotoxicity and produce interferon-gamma, when isolated from blood, lymphoid organs, lung, liver and uterus. Here we identify in dermis, gut lamina propria and cryptopatches, very distinct populations of NKp46+CD3- cells with reduced ability to degranulate and to produce interferon-gamma. In gut, the transcription factor RORgamma-t and CD127 (IL-7R alpha) defined a novel subset of NKp46+CD3- that is reminiscent of lymphoid tissue inducer (LTi)-like cells. Gut ROR gamma t+NKp46+ cells produced IL-22 in contrast to ROR-gamma t-independent lamina propria and dermis NK cells. These data show that LTi-like cells and NK cells share unanticipated similarities and reveal the heterogeneity of NKp46+CD3- cells in innate immunity, lymphoid organization and local tissue repair.
